MAGNETIC MOTOR 2 Sheets-Sheet Original Filed June 11. 1926 INVENTOR Jzlq G Hymns/mos %e@wn ATTORN EY washers at their upper ends,

ture, opposite the ivot is an arm 40 carryin a counter-weig t41.

post 42 rising from the base 10 carries an adjustable screw 43 provided with a clamping screw 44 and having at its inner end a spring bumper 45 against which the armature'38 makes contact at the end of its outward oscillative movement.

A link 46 connects the armature arm 40 with the cam plate 28 and it is to be noted that the point of link connection with the plate is such as to give the same an initial oscillatory movement on the pivot 27, stressing the spring 29, preliminary to transmitting movement to the arm 24 and stressing the arm return spring 25, this action releasing the roll 31 from the disc 21 when the arm is swung anti-clock-wise by the armature, the roll, moving with the plate, instantly gripping the disc upon return movement of the arm as indicated in the detail views in Figs. 5 and 6, the foregoing elements completing the purely mes'prings constitute resilient means opposing the rocking movement of arm 24 .in'one direction, and the cam roll, the plate 28, etc., provide means for establishing a driving connection between the arm and the disc. The operation of the means is to permit relative movement of the arm and disc in one direction but to prevent such relative movement in the opposite direction.

At the rear of the base are secured two upright rods 47 provided with nuts and each rod having two separate helically coiled springs 48, between the adjacent ends of each pair of which is disposed a non-conducting body 49 This body is formed with clearance openings through which the rods freely pass and I is thus floatingly supported so that no shocks or jars may be transmitted to it.

Mounted in the dielectric body 49 are two conducting strips 50 and 51 rigidly held at one end by a clamp bolt 52 and depressible into a recess in the upper portion of the body, these strips being of unlike material,

one of which is subject to greater elongation in the presence of heat than the other,

. whereby movement of the strips at their free ends is attained.

These strips are encased in a heat insulating covering 53 enclosed by a wire coil 54 one end of which is in electrical contact with the bolt 52 and the other end similarly engaged with a bolt 55, see Fig. 3.

A contact plate 56 is normally engaged by the bared free end of the strip 50, the plate being held to the body by a bolt-57.

An electrical current is supplied from any convenient source through insulated wires 58 and 59 held in a conductor cable 60 passin" through the base as shown in Fig; 1.

I411 electro-magnetic coil 61 is wound on hanical'" details of the apparatus. The

the arm 37 of the magnet core, to which current is supplied through wires 62 and 63, connected respectively to the bolts 55 and 52, enclosed in a cable 64.

In operation current enters through conductor 59, bolt 57 and contact plate 56 passes through the thermal elements 50, 51 to the bolt 52 and thence through "conductor 63 to coil 61, energizing the electro-magnet and attracting the armature 38.

This action tilts the cam plate 28, releasing the roll 31 from disc 21 and draws the arm 24 against the tension of the spring 25.

At the same time current through the conductor 58, and bolt 55 enters the coil 54 and passes to the bolt 52, heating the coil and causing curvature of the thermal strips and breaking contact withthe plate 56 thereby dee nerglzing the electro-magnet and permitting the pull of the spring 25 to move the armature into the position shown in Fig. 1, the armature being cushioned by contact with the adjustable bufier spring 45. The thermostatic switch affords one convenient means for periodically interruptingthe flow of current to the electromagnet.

As the armature is oscillated in one direction, the driving means are rendered effective to establish a connection between the arm and the disc, so that a rotary impulse is imparted to the spindle, and as the turntable is of considerable weight, it acts as a fly-wheel, maintaining an essentially uniform rotary movement during the 'momen tary cessation of advance impulses.

The thermal strips-upon breaking contact with the plate 56 quickly cool and automatically renew their contact with the plate,

whereupon a continuous succession of im-' pulses is obtained.
